Question

What is the sum of 1.57 and 6.88?

7 tenths, 3 hundredths, and 5 thousandths
8 ones, 4 tenths, and 5 hundredths
5 ones, 4 tenths, and 8 hundredths
7 tenths, 4 hundredths, and 5 thousand

Answer 1

8 ones 4 tenths 5 hundredths

add behind the decimal first. 57+88=145

now add the one to the ones place because if your adding 2-digit numbers you should only have a 2-digit answer.

so now you have 8.45
